-# Nginx Alpine
-基于的 Alpine(v3.11) 系统的 Nginx 镜像，用于提供 WEB(nginx) 服务。
-
-
-
-## 基本信息
-
-* 镜像地址：endial/nginx-alpine:v1.16.1
-* 依赖镜像：endial/alpine:v3.11
-
-
-
-## 数据卷
-
-```
- /srv/www			# 站点源文件
- /srv/conf			# nginx 配置文件，配置文件存放在 nginx 子目录中
- /var/log			# 日志文件，nginx 日志存放在子目录 nginx 中
- /var/run			# 进程运行PID文件，及Socket通讯文件
-```
-
-
-
-## 使用说明
-
-定义环境变量：
-
-```shell
-# 确定数据卷存储位置，可使用分散的目录或集中存储
-export DOCKER_VOLUME_BASE=</volumes/path>
-```
-
-- 注意修改主文件路径为实际路径
-
-
-
-### 运行容器
-
-生成并运行一个新的容器：
-
-```bash
-docker run -d --name nginx \
-  -p 80:80 \
-  -v $DOCKER_VOLUME_BASE/srv/www:/srv/www:ro \
-  -v $DOCKER_VOLUME_BASE/var/log:/var/log \
-  -v $DOCKER_VOLUME_BASE/srv/conf:/srv/conf \
-  endial/nginx-alpine:v1.16.1
-```
-
-
-如果存在`dvc`数据容器，可以使用以下命令：
-
-```bash
-docker run -d --name nginx \
-  -p 80:80 \
-  --volumes-from dvc \
-  endial/nginx-alpine:v1.16.1
-```
